UNITED STATES PATENT OFFIC FRANK CHASE, OF WATERVILLE, MAINE, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE UNITED SHOE MACHINERY COMPANY, A CORPORATION OF NEW JERSEY.

LASTING-MACI-IINE.

Specification of Letters Patent. Patented Sept. 28, 1909.

Application filed June 14, 1899. Serial No. 720,442.

To all whom it may concern:

Be it known that I, FRANK CHASE, of Waterville, county of Kennebec, State of Maine, have invented certain Improvements in Lasting-Machines, of which the following, read in connection with the accompanying drawings, is a specification.

This invention relates to lasting machines and particularly to novel means for stretching the upper and laying the edge portion of the upper over on the innersole.

It is one of the objects of the invention to provide mechanism for stretching and overlaying the upper without danger of injury to the upper materials and to this end a very important feature of the invention consists in providing means for actuating the uppermanipulating devices with constant force during their movements for working the upper into lasted position.

In the embodiment of the invention herein shown the upper-manipulating devices are actuated by frictionally controlled mechanism, and preferably provision is made whereby the foree with which said devices are moved may be regulated according to the conditions of the work by adjusting the parts to increase or diminish the friction.

Another feature of the invention consists in providing novel means for stretching the upper and laying it over the innersole in position to be secured thereto. As herein shown, this means includes grippers for gripping the upper and means for relatively moving the last and the grippers for pulling the upper over and down toward the innersole of the shoe. The means for effecting this relative movement is shown as including a shoe-engaging means adapted to be actuated for carrying the shoe downwardly away from the grippers and then laterally and upwardly toward the grippers, said two movements effecting the stretching of the upper and the overlaying of the edge portion of the upper on the innersole. Preferably the grippers will be closed to grip the upper by the novel actuating means above referred to by which all danger is avoided of the grippers grasping the upper with too great force so that the upper will be cut or otherwise injured. Preferably also the shoe-engaging means is moved for effecting the stretching of the upper by similar novel actuating means, whereby the upper is pulled by a constant or uniform force, the frictionally engaged members of the actuating means slipping when the resistance to further stretching exceeds the force produced by the adjustment of the fI'lCt-l0l1ClG veloping means. A. movable edge rest is preferably employed, said rest being adapted to position the shoe while the upper is being stretched and to be retracted or withdrawn for permitting the lateral movement of the shoe for laying the upper over upon the innersole.

Means is herein shown for automatically retracting the edge restand for automatically actuating the shoe-engaging means for carrying the shoe laterally under the grippers to cause the upper to be overlaid on the innersole, although both the edge rest and the. shoe-engaging means might be manually moved for the purposes stated if desired. As illustrated, the shoe-engaging means comprises a pivoted member which is arranged to turn about its axis for carrying the shoe in a curved path laterally and upwardly whereby the edge portion of the upper is carried over and laid down on the innersole in position to be secured thereto. As herein shown, one of the gripper members is formed with a driver passage and the shoe-engaging means is arranged to carry the shoe under said gripper member into position for a fastening to be driven from the driver passage into the overlaid upper and innersole for securing the upper in lasted position.

The movable edge rest and the shoe-engaging means serve to position the shoe in operative relation to the grippers and then in operative relation to the mechanism for inserting fastenings, and when the shoeengaging means is mechanically actuated for moving the shoe laterally, as herein shown, it carries the shoe inwardly a predetermined distance at each operation and insures the positioning of the shoe to receive the fastenings a uniform distance from the edge of the shoe. This feature of the invention which consists in providing means for insuring that the shoe shall be moved inwardly with the movable edge rest to insure the insertion of fastenings at a predetermined distance from the edge of the shoe may obviously be of use in other machines for inserting fastenings.

Other features of the invent-ion. including certain details of construction and con'ibinations of parts, will be explained in the fol lowing description and pointed out in the claims.

Fig. 1.1 is a similar view showing the position of the same parts after the last has been moved laterally for carrying the shoe under the grippers for laying the upper over on the innersole.

The machine herein shown as embodying on a suitable standard A and provided with bearings for a shaft 2 upon which is loosely mounted the driving pulley 3 adapted to be connected to and disconnected from said shaft by a manually controlled clutch. As herein shown, the pulley comprises a relatively wide flange and a thin web arranged to pro vide chambers in. either side of the pulley. A circular block 12 is adapted to fit into and partially fill the recess in the rear side of the pulley, said block being provided with a hub and secured to the driving shaft by a screw 14. The block is provided with a radial slot in which is guided a slide 10 normally pressed inwardly by a spring 13, but adapted to be forced outwardly into engagement with a projection 16 on the inner wall of the pulley for causing the block and the shaft to which it is secured to be rotated by the pulley. The slide 10 is arranged to be actuated outwardly into engagement with the pulley for starting the machine by a longitudinally movable spindle 7 mounted in an axial recess in the shaft and having a beveled inner end adapted to be forced into engagement with and to actuate the slide. The outer end of the spindle 7 is connected by a binding screw 9 to a swiveled block 8 in the upper end of a rocking arm 6 to Which connected with a foot is attached a r0u o treadle not shown. Downward movement the starting of the machine.

suitably secured thereto.

engagement withthe slide 10 and permits the spring 13 to force the slide out of engagement with the projection 16 on the pulley whereby the shaft is disconnected from the pulley and allowed to come to rest. Reverse movement of the several parts effects Any other usual or suitable form of clutch mechanism might be substituted for that above described for starting and stopping the machine. The machine is provided with mechanism for supplying and driving tack-s for securing the upper to the innersole after it hals been stretched and overlaid on the innerso e.

The hop )er 22 for containing the tacks and the means for presenting them in position to be drivenis or may be substantially the same as that shown in my prior United States Letters Patent No. 547,662, of October 8, 1895. The hopper of that patent contains a feed table which requires to be oscillated for facilitating the delivery of the tacks. As herein shown, a rod 20 is operat-ively connected with said feed table and is arranged for longitudinal movement in bearings formed in or connected to the head 13. The inner end of the rod 20 is provided with a roll adapted to be engaged by a cam 18 secured by a screw 17 to the web of the pulley 3, as shown most clearly in Fig. The rod is acted upon by-a spring 21 which holds the roll normally against the cam and effects the movement of the rod and its connected feed table in one direction. Any other suitable connection between the feed table and a mov ing part of the machine may be employed for oscillating the table.

The shaft 2 on its outer end is provided with ahead located in a suitably formed recess in the frame and with a crank pin 23, see Fig. 3 and dotted lines in Fig. 1. The crank pin is connected by a vertical link 24 with the driver bar 25 which is arranged to reciprocate in a guideway formed between the outer face of the head and a cap plate The driver bar supports the hammer rod 26 by means of which the tacks fed from the hopper are inserted for securing the upper to the innersole. The cap plate above referred to is provided with forwardly extending lugs in which are formed bearings for a shaft 29 to which is secured a friction disk 28. The friction disk has a laterally extending lug, see dotted lines in Fig. 1 and full lines in Fig. 5, which is connected by links X26 and 27 to the driver bar 25, whereby the friction disk and shaft are oscillated by the movements of the driver bar up and down. Mounted upon the shaft 29 at opposite sides of the friction disk 28 are disks 30 and 31 normally pressed against the friction disk 28 a l and a movable member or jaw i0.

by springs 36 and 37 located between collars Stand and adjustable nuts- 32 and 33 on the ends of the shaft 29; The force with which thedisks30 and 31 are pressed against the friction disk 28* may be independently varied by adjusting the nuts 32 and 33. mounted for rotative movement with the friotiondisk'28, but either of them will slip witlrrelation tothedisk 28 whenever the resistance to: its movement overcomes the f-riction=between that disk and the disk 28'.

The upper is adapted to be gripped by grippers com-prising in fixed member or jaw- The member-40 isformed' on the-lower end of a lever 39 fulcrumed on a pivot pin 44- 39 asshown iii-Figs.- 1=, 2, ands.v Themeansherein: provided for closingthe grippers has the advantage that the grippers will gripiw-itlr thesame force stock differing to any extent inthickness, the actuator disk slipping-with relation to the friction disk 28 af-terthegrippershave closed upon the stock,

so that the force wit-h which the upper is gripped is constant and uniform, whatever the thickness-0f the stock.

Asherein shown, the gripper member or jaw 41 is formedonthe block 42 which is notched or recessed, as indicated in Figs.

1 and 9, and the cotiperating gripper me m-- her or jaw l0'has a relatively narrow gripp111gftICG"-Wl11(3ll is adapted to-be received 1n the notch-or recess of the othergripper member, whereby the stockgripped between the aws-1s bent or crimped so that it is firmly held by the grippers without being'clamped with sufiicient force to out the stock or to indent it to an objectionable extent.

In the embodiment of the invention here-- in shown, the upperisstretched, after having' been gripped, by amovement of the last orshoe downwardly away fronrthe grippers, and to thisend themachine isprovided with shoe-engaging means comprising preferably aplurality of bars 51 arranged upon opposite sides of the gripperlever 39, as shown in Figs. 1 2, and 5.- The two bars engage the shoebottom at points separatedfrom each: other far enough to avoid liability of the shoe being canted while being depressed, tliusinsuring that the upper shall not be pulled laterally out of place. The disk. 31'

forms a: frictionally controlled actuator by means of Whichthebars 51- are movedlongitudinally for depressing the last or shoe, and

to this end said diskis connected by a link 50 to the upper endsof said'bars, as shown: in

The disks 30 and 31 are thus- "been retracted.

Figs. 1' and 5. The actuator disk 31 is adapted to slip with relation to the friction disk 28- whenever the tension on the upper being stretched exceeds the frictional grip of said actuator disk upon the disk 28, and this may be determined and regulated by adjusting the nut 38 to increase or diminish the force I preferably by a movement of the shoe laterally and upwardly under the grippers, and as herein shown, the bars 51 are pivot-ally mounted and are arranged for turning-move ment to carry the shoe engaged by them under the grippers. To this end the bars are slotted, as indicated at in Fig. 5, and

receive a slide block 54 mounted on the pivot pin 4:4 about which the gripper lever 39 turns, as heretofore described. This construction permits the bars 51 to be moved longitudinally for forcing the shoe downwardly to stretch the upper and allows said bars to be turned for carrying the shoe under the grippers to. overlay the edge portion of the upper upon the innersole. An edge rest 52 is preferably employed for determining the lateral position of the shoe with relation to the grippers and bars 51 during the stretching of the upper. In order to permit the shoe to be moved under the grippers for overlaying the edge portion of the upper on the innersole, the edge rest requires to be retracted or withdrawn. This may be done manually or automatically.

As herein shown, I have provided means for automatically withdrawing the ed rest to permit the shoe to be carried by the bars 51 under the grippers, and to this end a cam block (31 issecurod to the shaft 2 by the binding screw l-lbefore mentioned. A lever (32 pivoted at 63 carries upon its upper end a rolll which. stands in the groove of the cam block. The lower end of the lever 62' is connected to the slide (34- wliirh is li'nigitudh -ally movable in gniderays in t machine frame and to the front end of. said slide (it the edge rest is secured. The cam (31 is so formed that the edge rest will be retra d immediately after the shoe-engaging bars have forced the shoe downnuirdly for s etching the upper. The shoe-engaging ba .nay be turned. for: carrying the shoe under the grippers either simultaneously with the with.- dra'\val:of. the edge rest or after the rest has The turning movement of, thebars may be effected m .ially, by the operator forcing the shoe terally toward the machine, or: the bars may be turned by mechanism actuated from some moving part did of the machine. As herein shown, the connection between the upper ends of the bars and the actuator disk 31 tends to turn the bars after they have been moved longitudinally, and I have also shown means connected with the lower ends of the bars for effecting their turning movement. This means includes a connection, by means of links 65, between the lower ends of the bars 51 and the front end of the slide 64L by means of which the edge rest 52 is actuated. This connection causes the bars to be turned in the direction for carrying the shoe under the grippers at the same time that the edge rest is retracted. The means connected with the lower ends of the shoeengaging bars for turning said bars is shown as positively actuated and this arrangen'ient has the advantage that the shoe is caused to follow the edge rest in its inner movement, being carried laterally to approximately the same position at each operation whereby all the securing tacks will be inserted at substantially the same distance from the edge of the shoe. In the inward movement of the shoe under the grippers the edge portion of the upper between the edge of the last and the grippers is carried under tension into substantial alinement with that portion which is engaged by the grippers, as may be seen from Fig. 11. In the event that this lateral movement of the shoe is in excess of the length of the upper between the edge of the last and the grippers, as it might be if an upper were particularly inelastic, the upper will slip between the grippers to permit the full amount of lateral movement provided for by the throw of the cam (31, if that cam is employed for effecting lateral movement of the shoe.

It will be seen that with the construction above described the shoe is moved by the bars 51 first downwardly away from the grippers for stretching the upper and the shoe is then moved laterally and upwardly in a curved path toward the grippers whereby it is carried under the grippers and at the same time moved toward the grippers and the upper is overlaid upon the innersole in position to be secured thereto. It is of course not essential that the bars 51 be mounted to turn about a pivot and thus carry the shoe inwardly and upwardly in a curved path, as obviously the movement of the shoe for overlaying the upper upon the innersole might be in a straight line and be controlled by any desired arrangement of the bars or other suitable means. Preferably and as herein shown, the driver passage 43 is formed in the fixed gripper member, as indicated in Fig. 11, so that the shoe in being moved into position for overlaying the upper is carried under the driver passage in position to receive the securing tack which is inserted in the final descent of the driver bar.

The positive movement of the shoe inwardly as described insures that it shall follow the edge rest in the inward as well as in the outward movement of the latter and be accurately positioned alternately in two relations to the tack driver passage and also to the grippers.

. Specific claims are not herein made to the combination with fastening inserting mechanism of means for positively moving the shoe both inwardly and outwardly to insure the insertion of fastenings in any predetermined position. The right is reserved to claim this feature of the invention in a separate application.

In using the machine the shoe is prepared for lasting by placing the upper materials about the last and the innersole upon the last bottom and then drawing the upper over at the toe and sides in each of which places it may be secured to the innersole for holding it in position upon the last. The shoe is then supported in the hands of the workman and rested bottom upwardly against the gripper member 40, as shown in Fig. 9, the side of the shoe bearing against the edge rest 52 and the edge portion of the upper being located between the two gripper members, the machine having been stopped in such position that the grippers are open. The machine is now put into operation by actuating the rod 5 to effect the engagement of the clutch members for turning the shaft 2 and the driver bar 25 begins to descend. During the first portion of its descent motion is imparted thereby through the links X and 27 to the friction disk 28 and through said friction disk to the actuator 30 for swinging the lever 39 to close the grippers, the gripping tension being applied yieldingly through said frictionally controlled actuator. During the continued downward movement of the driver bar 25 and the rotation of the friction disk 28 the actuator 31 effects the downward movement of the bars 51 and consequently of the last or shoe, whereby the gripped upper is stretched or strained over the last upwardly, the shoe being ultimately depressed preferably to a position where said strain exceeds the tension between the friction disk 28 and the actuator 81, so that the upper is stretched with a force predetermined by the adjustment for the frictionally controlled actuator. The edge rest 52 is next retracted and the shoe moved laterally and upwardly under and toward the grippers, this lateral movement of the shoe being effected in any one of the ways described or in any other suitable way whereby the shoe is carried inwardly and upwardly for overlaying the upper upon the innersole and positioning the shoe to receive the fastening tack, which in the ment of the driving shaft after the tack has been inserted the driver bar is lifted andthe several parts are restored to their initial positions ready to repeat the operation for lastlng another section ofthe shoe,.the lasting operation as a whole being carried out by repeated operations of the machine applied to different portions of the upperat different times.

38. A shoe lasting machine having, in combination, grippers, a tacker, and mechanism for relatively moving the shoe and the grippers to strain the upper and for then moving the shoe into the field of operation of the tacker while the grippers maintain the pulling strain.

39. A shoe lasting machine having, in combination, grippers, a tacker, and mechanism for relatively moving the shoe and the grippers to strain the upper, and, while holding the upper under tension, moving the shoe laterally and upwardly in a curved path into position for the tacker to insert a fastening through the gripper held upper.

40. A shoe lasting machine having, in combination, grippers, and a tacker relatively immovable laterally of the shoe, and mechanism for relatively moving the shoe and the grippers to strain the upper and then, while the grippers continue to hold the upper, moving the shoe to position it for receiving the operation of the tacker.

41. A shoelasting machine having, in combination, grippers, a tacker working through one jaw of the grippers, and mechanism for relatively moving the shoe and the grippers to strain the upper, and then, ,while holding the upper under tension, moving the shoe obliquely to the first movement to position the shoe for receiving the tack in the pulled upper.

42. A machine for working an upper over a last having, in combination, grippers to seize the upper and lay it inwardly over the edge of the last, a tacker associated with the grippers, means for actuating the grippers to seize the upper, means for relatively actuating the last and the grippers and. tacker together to overlay the upper and position the shoe and the tacker for a tack to be inserted to secure the upper, and means for actuating the tacker to insert the tack.
